India to Include TOPCon/HJT Modules in Green Procurement List

On May 10, 2026, India’s Ministry of New and Renewable Energy (MNRE) released the draft Green Solar Procurement Framework, proposing mandatory green procurement for TOPCon and HJT photovoltaic modules starting October 2026. The policy requires bidders to submit internationally verified Life Cycle Assessment (LCA) carbon footprint reports (per ISO 14040/14044), with a cap of ≤380 g CO₂e per watt-peak (Wp). This development is particularly relevant for solar module exporters, LCA service providers, certification bodies, and supply chain stakeholders engaged in India-bound solar trade.

Event Overview

On May 10, 2026, the Indian Ministry of New and Renewable Energy (MNRE) published the draft Green Solar Procurement Framework for public consultation. The draft proposes that, effective October 2026, TOPCon and Heterojunction (HJT) photovoltaic modules be added to India’s national green procurement mandatory list. Under the framework, all bidding manufacturers must provide third-party-verified Life Cycle Assessment (LCA) carbon footprint data compliant with ISO 14040 and ISO 14044 standards, and demonstrate a unit Wp carbon footprint no greater than 380 g CO₂e. Six leading Chinese manufacturers of TOPCon/HJT modules have submitted their initial LCA datasets to the Confederation of Indian Industry (CII) Green Certification Centre.

Which Sub-Sectors Are Affected

Direct Exporters & Module Manufacturers

Manufacturers supplying TOPCon or HJT modules to Indian government or PSUs tenders will face new compliance requirements. The impact manifests in mandatory LCA reporting, verification timelines, and potential disqualification if carbon intensity exceeds the 380 g CO₂e/Wp threshold — even if technical and pricing criteria are met.

Raw Material & Component Suppliers

Suppliers of silicon wafers, metallization pastes, encapsulants, and glass used in TOPCon/HJT production may experience upstream demand for low-carbon material declarations. While not directly regulated, their input data contributes significantly to downstream LCA outcomes — making traceability and supplier-level environmental data more operationally relevant.

Manufacturing & Cell Production Facilities

Cell and module fabrication plants — especially those using high-energy processes like PECVD for HJT or boron diffusion for n-type TOPCon — may need to review energy sourcing, grid mix assumptions, and on-site renewable usage, as these factors directly affect LCA results under ISO-compliant system boundaries.

Certification & Verification Service Providers

Third-party LCA verifiers accredited for ISO 14040/14044 — particularly those with experience in PV manufacturing systems and Indian regulatory engagement — are likely to see increased demand for audit capacity and localized interpretation of MNRE’s upcoming guidance documents.

What Relevant Enterprises or Practitioners Should Focus On

Monitor official updates to the draft framework

The current version is a consultation draft. Stakeholders should track MNRE’s final notification, including any adjustments to the carbon threshold, scope boundaries (e.g., cradle-to-gate vs. cradle-to-grave), or acceptable verification bodies — all of which may shift implementation expectations.

Verify whether your product category falls within scope

The requirement applies specifically to TOPCon and HJT modules tendered under MNRE-led programs (e.g., CPSU Scheme, ISTS projects). PERC, Al-BSF, or thin-film modules are not included at this stage. Exporters should confirm tender eligibility criteria before initiating LCA work.

Distinguish between policy signal and enforceable obligation

As of May 2026, the framework remains in draft form. Its adoption, enforcement timeline, and penalties for non-compliance are not yet codified. Companies should treat early LCA submissions as preparatory — not evidence of imminent enforcement — unless MNRE issues binding instructions.

Prepare internal data collection infrastructure

Manufacturers should begin mapping energy consumption, material inputs, transportation logistics, and waste generation across production lines. ISO-compliant LCA requires granular, auditable primary data — not estimates — and building this capability takes time, especially for multi-site operations.

Editorial Perspective / Industry Observation

Observably, this initiative signals India’s intent to align domestic clean energy procurement with global decarbonization norms — particularly those emerging in the EU (e.g., CBAM, Ecodesign for PV) and Japan. Analysis shows it is currently a procedural signal rather than an operational mandate: no penalties, no finalized verification protocols, and no retroactive application are specified. From an industry perspective, its significance lies less in immediate compliance burden and more in its role as an early indicator of how climate-related procurement criteria may cascade into other G20 markets. Continued attention is warranted because MNRE’s approach could inform similar frameworks in Southeast Asia or Africa where Indian public sector procurement models are increasingly referenced.

India’s proposed green procurement rule for TOPCon and HJT modules reflects a targeted step toward embedding carbon accountability into solar project deployment — not a broad-based market barrier, but a calibrated policy lever affecting specific technology segments and procurement channels. At present, it is best understood as a forward-looking benchmarking exercise, one that prioritizes transparency and data readiness over immediate enforcement.
